Definitions

  • the demarcation between the aureole and the surrounding blue halo may be displaced one way or the other by modification of the electricconstants, more particularly of the current intensity, of the size of the electrodes, of the power of emission and of other variables, and in this way lamps with various light efiects may be produced, name- 1y lamps with an orange-red core of different size surrounded by a blue halo, or lamps emitting a white light.
